+
+NOTE: You can also install Maven (>=3.3.3) yourself and run the `mvn` command
+in place of `./mvnw` in the examples below. If you do that you also
+might need to add `-P spring` if your local Maven settings do not
+contain repository declarations for spring pre-release artifacts.
+
+NOTE: Be aware that you might need to increase the amount of memory
+available to Maven by setting a `MAVEN_OPTS` environment variable with
+a value like `-Xmx512m -XX:MaxPermSize=128m`. We try to cover this in
+the `.mvn` configuration, so if you find you have to do it to make a
+build succeed, please raise a ticket to get the settings added to
+source control.
+
+The projects that require middleware (i.e. Redis) for testing generally
+require that a local instance of [Docker](https://www.docker.com/get-started) is installed and running.
+
+
+=== Documentation
+
+The spring-cloud-build module has a "docs" profile, and if you switch
+that on it will try to build asciidoc sources from
+`src/main/asciidoc`. As part of that process it will look for a
+`README.adoc` and process it by loading all the includes, but not
+parsing or rendering it, just copying it to `${main.basedir}`
+(defaults to `${basedir}`, i.e. the root of the project). If there are
+any changes in the README it will then show up after a Maven build as
+a modified file in the correct place. Just commit it and push the change.
+
+=== Working with the code
+If you don't have an IDE preference we would recommend that you use
+https://www.springsource.com/developer/sts[Spring Tools Suite] or
+https://eclipse.org[Eclipse] when working with the code. We use the
+https://eclipse.org/m2e/[m2eclipse] eclipse plugin for maven support. Other IDEs and tools
+should also work without issue as long as they use Maven 3.3.3 or better.
+
+==== Activate the Spring Maven profile
+Spring Cloud projects require the 'spring' Maven profile to be activated to resolve
+the spring milestone and snapshot repositories. Use your preferred IDE to set this
+profile to be active, or you may experience build errors.
+
+==== Importing into eclipse with m2eclipse
+We recommend the https://eclipse.org/m2e/[m2eclipse] eclipse plugin when working with
+eclipse. If you don't already have m2eclipse installed it is available from the "eclipse
+marketplace".
+
+NOTE: Older versions of m2e do not support Maven 3.3, so once the
+projects are imported into Eclipse you will also need to tell
+m2eclipse to use the right profile for the projects.  If you
+see many different errors related to the POMs in the projects, check
+that you have an up to date installation.  If you can't upgrade m2e,
+add the "spring" profile to your `settings.xml`. Alternatively you can
+copy the repository settings from the "spring" profile of the parent
+pom into your `settings.xml`.
+
+==== Importing into eclipse without m2eclipse
+If you prefer not to use m2eclipse you can generate eclipse project metadata using the
+following command:
+
+[indent=0]
+----
+	$ ./mvnw eclipse:eclipse
+----
+
+The generated eclipse projects can be imported by selecting `import existing projects`
+from the `file` menu.
